PENGARUH SIKAP KERJA DUDUK PADA KURSI KERJA YANG TIDAK ERGONOMIS TERHADAP KELUHAN OTOT-OTOT SKELETAL BAGI PEKERJA WANITA BAGIAN MESIN CUCUK DI PT ISKANDAR INDAH PRINTING TEXTILE SURAKARTA

Women labours cucuk machine part PT Iskandar Indah Printing Textile total is 25 person, such as two shift time (morning and afternoon). When working at field, labour cucuk machine partuse work chair unergonomic. This chair just includes sit layer, and four of foot chair. Unergonomic work chair (not fit by size of body labour and chair design), so there’s not comfort labours in working. This not appropriate can cause skeletal muscle injure of labours. The purpose of research for understand appropriate between chair size and anthropometry woman labours part of cucuk machine in PT Iskandar Indah Printing TextileSurakarta, for finding impact of work sit posture at work chair unergonomic to skeletal muscle injure of woman labour part cucuk machine in PT Iskandar Indah Printing TextileSurakarta, and for know part of skeletal which dominant get injure. The research is descriptive analytic and pre post test design by cross sectional. Population of woman labour cucuk machine in PT Iskandar Indah Printing Textile Surakarta is 25 person. The sample is 25 person. Sampling used total sampling. Data collate by observation, measurement and used questioner method. Data analysis of research used paired T-Test.
